For fear of the deficiencies in the prior art part, the utility model proposes a kind of surface evaporation drying of utilizing, obtain comprehensive regulation black liquid, effectively organic device in the extraction and application black liquor.Its cardinal principle is that black liquor is formed the black liquor film on specific device, and its continuous heating is reached rapid evaporation black liquor moisture, the purpose of the dry thing of separating solids.
Technological thought of the present utility model is that one of design utilizes dry gas, realizes the automation equipment of the continuous heating evaporation drying of black liquor, it is characterized in that: go up at support (2) drum assembly is installed, the two ends design of drum assembly has air flue manhole appendix A, B; Hopper (1) is installed in the below of drum assembly, and a side is installed doctor blade device (22), and spiral deflector chute (18) designs in the below of doctor blade device (22), is scraped by scraper by the dry good material of cylinder surface, places spiral deflector chute (18);
Drum assembly can adopt the branch body structure, is made up of cylindrical shell (11), the sharp bearing of end cap (12) (8).Design and installation master end, the both sides end cap (10) of cylindrical shell (11) and passive side end cap (14), the center of two end cap is processed with air flue manhole appendix A, B.The two ends of cylindrical shell (11) stud with opposite opened rolling bearing (8), are connected with motor (3) by gear wheel (9).
Deflector chute (18) is gone up minor sprocket (5) and is connected with hinge wheel (7) on the master end end cap (10) by chain, and when drum assembly rotated, spiral deflector chute (18) quilt was driven running, and dry thing is transferred out.
The doctor blade device (22) of drum assembly one side adopts spring top clamping formula doctor blade device, its upper design seal closure (21),
Hopper (1) can adopt arcuate structure, and black liquor fluid level controller (19) and film thickness controller (20) wherein can be installed, and in order to the liquid level height of control liquid level in hopper, adheres to the thickness and the uniformity of black liquor material film on the control cylindrical shell.
Above drum assembly, be provided with seal closure (12) and water collecting dike (13), the water vapour that is used for material is evaporated is extracted out, and cooling water is derived.
The flue gas that superheated vapor can adopt boiler to discharge, various paper mills

The utility model will be in conjunction with the embodiments (accompanying drawing) be further described:
Drum assembly of the present utility model is made up of cylindrical shell (11), master end end cap (10) and passive side end cap (12), links together by bolt nut.Cylindrical shell (11) is an ironcasting, and long 2.5 meters, diameter is 1.5 meters.The two ends of drum assembly are supported by support (2), stud with opposite opened rolling bearing (8) on the support (2), can make cylinder choosing transhipment moving.There are air flue manhole appendix A, B in the center of end cap (10) and end cap (12), and the aperture is Φ 450mm.Motor (3) is connected with the gear wheel (9) of drum assembly by reductor (6), and gear wheel (9) is installed on the master end end cap (10), electric motor starting, cylinder rotation.The drum assembly below is provided with hopper (1), adopts arcuate structure, places concentrated black liquid in the hopper (1).Black liquor fluid level controller (19) and film thickness controller (20) can be installed in the hopper,, adhere to the thickness and the uniformity of black liquor material film on the control cylindrical shell in order to the liquid level height of control liquid level in hopper; The doctor blade device (22) that drum assembly one side is installed, adopts spring item compact form doctor blade device by long 2.3 meters; Its below be spiral deflector chute (18), and minor sprocket (5) is connected with hinge wheel (7) on the master end end cap (10) by chain on the deflector chute (18).
Work as electric motor starting, small belt pulley (3) drives big belt pulley (4), and the pinion drive gear wheel (9) by reductor (6) makes drum assembly rotate.Air flue manhole appendix A, B circulation temperature by two end cap in the cylinder of rotation reaches 450 ℃ flue gas, when the cylindrical shell that high temperature rolls passes through the arc hopper, is stained with the very thin concentrated black liquid of one deck.When cylinder rotates to
During circle, concentrated black liquid is heated as dry thing, is scraped by the scraper of cylinder one side, falls within the spiral deflector chute (18).Deflector chute (18) is promoting dry substance material to C place and is being collected under minor sprocket (5) and hinge wheel (7) drive.
